Energobudget of young sturgeon fishes in constant, variablethermoregimes and at free swimming in thermogradient space.

摘要

Experiments were performed on comparative estimation of metabolism and energobudget of young sturgeon fishes (Acipenser baerii, Acipenser ruthenus under conditions of constants or variable thermoregimes and at free swimming in the thermogradient space in the Seliger Lake and Ivankovskoye Reservoir (Russia). It is shown, that in conditions of free swimming young sturgeon fishes in thermogradient space the greatest effect of optimization energobudget is provided: acceleration of growth, reduction of the oxygen consumption per unit of body mass gain, increase of a degree of using of the consumed food on growth.
